New subject: [Users] what difference between route and failure_route when using rewriteuri

15 Mar 2006


      Hi all,
  I wanna to use rewriteuri to forward calls to next
gw when call to last gw fail. My testing's script like
this:
route[1]
{
        if (!t_relay()) {
                sl_reply_error();
        };
}
failure_route[1] {
        if(t_check_status("(408)|(404)|(403)")) {
revert_uri();
rewriteuri("sip:10001802@172.25.16.121:5060");
                route(1);
                return(0);
        };
        return(0);
}
But it worked like this(when timeout):
 22.960402 172.25.16.250 -> 10.0.0.2     SIP Status:
500 I'm terribly sorry, server error occurred (1/SL)
 22.960462 172.25.16.250 -> 10.0.0.2     SIP Status:
408 Request Timeout
That is first it send an 500 error, then send an 408
timeout errro
I try it in route like this
route {
...
if(method=="INVITE") {
rewriteuri("sip:10001802@172.25.16.121:5060");
               route(1);
               return(0);
       };
...
}
It work fine.
What's wrong with my scripts?
Thanks
Br,
Jimway
